Chapter 3: Connecting the Data and Power Cables Special Instructions for use of Glands

phn-4026 003v000 Page 3-21

Special Instructions for use of Glands

Note

Each RFU-E unit is supplied with one gland. If additional glands are required, they must be ordered

separately, in kits of five glands each.

Table 12: Glands Kit

P/N Description

N000082L014A PTP 820 Glands_x5_KIT

In addition, gland caps can be ordered to protect the cable and connector from damage when elevating the cable and gland to the radio unit. See Step Error! Reference source not found. in Section Appendix , General Installation Procedure. Gland caps are ordered separately, in kits of 10 caps each.

Table 13: Gland Caps

P/N Description

N800082L009A PTP 820E Cable Protection Cap (Qty 10)

In order to remove the plastic plugs for the unit, you can use the flange of supplied glands to disconnect them. See figures below.


phn-4026 003v000 Page 3-22

General Installation Procedure This procedure applies to all cable types, and explains how to install the cables using long glands. The gland is

supplied assembled.

1. Before inserting a cable, you must disassemble the gland cap and gland rubber from the gland body.

2. Slide the gland cap into the cable.

3. Slide the gland rubber into the cable.


phn-4026 003v000 Page 3-23

4. Slide the cable into the body of the gland. If you are using a gland cap (see Step Error! Reference source

not found.), make sure to leave enough space for the gland cap to fit into the gland without disturbing the

cable.

5. Optionally, after securing the cable into the body of the gland, you can close the other side of the gland

with an M28 gland cap. The gland cap protects the cable and connector from damage when elevating the

cable and gland to the radio unit.

6. The M28 gland cap has a hook on top. After attaching the gland cap to the gland, you can connect a rope

to the hook and use this to lift the gland and cable up to the radio unit. Before screwing the gland into the

radio unit, you must remove the gland cap.


phn-4026 003v000 Page 3-24

7. If you used an M28 gland cap to close the gland when raising the gland and cable to the radio unit,

remove the gland cap from the gland at this point by unscrewing the cap.

8. Connect the cable to the port.

9. Screw the gland into the radio unit until there is full contact between the gland and the radio unit.


phn-4026 003v000 Page 3-25

Note

Before tightening the gland, make sure the gland is aligned with the tapped hole in the unit.

Tightening the gland at an angle can ruin the thread on the gland and prevent proper sealing of the

interface

10. Insert the main part of the gland into the thread in the radio body and tighten until there is full contact

and the gasket is fully contained between the gland and the radio and cannot be seen. Tighten the gland

gently and make sure there is no resistance. If there is resistance, stop immediately, and thread out the

gland. Verify that the gland thread is not damaged and tighten the gland again.

Note

Pay attention that the gland rubber is properly located and not damaged during the tightening of the

gland cap. If the gland thread is damaged do not use it!

11. Tighten the rear portion of the gland onto the main part of the gland and make sure that the main part of

the gland does not have an additional swivel after the rear portion is secured.

Note

If the main portion of the gland is rotated while the rear portion is seizing the cable, this may ruin the

cable connector.

To prepare the CAT-5e or CAT-6 cable and plug-in field:

1. Prepare the gland and insert the cable, as described in General Installation Procedure.

2. Strip off approximately 45 mm of the outer insulation jacket from the CAT-5e or CAT-6 cable.

3. Do not strip off the end of the cable shield, but rather, twist the shield to form a braid.


phn-4026 003v000 Page 3-35

4. Roll back the foil shield insulation and wrap the drain wire around the foil. Do not remove any insulation

from the conductors.

5. Align the colored wires.

Note: Cord colors should be matched to the same pins on both ends of the cable.

6. Trim all wires to the same length. About 12 mm on the left should be exposed from the inner sheath.

7. Separate the wires and place the twisted shield between the separated wires.

8. Insert the wires into the RJ45 plug. Verify that each wire is fully inserted into the front of the RJ45 plug

and in the correct order, according to the pinouts shown in Section Appendix , Outdoor CAT-5e Cable

Specifications. The sheath of the CAT-5e or CAT-6 cable should extend into the plug by about 13 mm and

held in place by the crimp.

9. Extend the cable jacket with the shield into the connector about 5 mm for strain relief and shielding

connection.

10. Wrap the twisted braid firmly around the cable jacket and let the crimping tail of the RJ45 plug envelop it.

Important Note! To ensure proper grounding, it is essential that the twisted braid be firmly

connected to the RJ45 plug.


phn-4026 003v000 Page 3-36

11. Crimp the RJ45 plug with the crimp tool. Make sure the twisted shield is crimped firmly to the RJ45 plug.

12. Verify that the wires ended up the correct order and that the wires extend to the front of the RJ45 plug

and make good contact with the metal contacts in the RJ45 plug.

13. Push back the CAT-5e or CAT-6 plug cover on the connector plug.

Note: It is recommended that the newly prepared cable be tested with a Cable Analyzer such as

the FLUKE DTX-1800 (or the equivalent), to make sure the cable complies with ANSI/TIA/EIA-568-B-2.

Make sure to verify both connectivity and grounding continuity at both ends of the cable.

Chapter 4: Generic Installation Procedures Torque Requirements

phn-4026 003v000 Page 4-40

Chapter 4: Generic Installation Procedures

Before starting an installation, use a leveler to make sure that the poles are 100% vertical. You need to check both

sides of each pole at 90 degrees separation. This is a critical step in any link but most important when installing

XPIC.

Torque Requirements When tightening the captive screws, use 20 Nm torque for radio-antenna, radio-mediation device, and mediation

device-antenna connections. In order to avoid misalignment, screws should be tightened progressively.

When fastening a waveguide to the radio or mediation device, use the following torque, according to frequency

and screw type:

• 6 GHz: M5/#10-32: 3.5 Nm

• 7/8-15 GHz: M4/#8-32: 2.5 Nm

• 18-42 GHz: M3/#4-40: 1Nm

Chapter 5: Installation Procedure and Antenna Alignment – 1+0 with 43 dBi Flat Antenna and Alignment Device

Torque Requirements

phn-4026 003v000 Page 5-41


When you order an RFU-E with a 43 dBi flat antenna, the radio and antenna are delivered together as a single unit.

The polarization is determined by the placement of the radio-antenna unit.

Figure 5: Installation and Alignment Device – Azimuth and Elevation Adjustment Tools

The installation and alignment device enables you to easily adjust the antenna’s azimuth and elevation, in gross

and fine intervals. Gross alignment enables you to adjust the azimuth and elevation in 15° increments. Fine

alignment enables you to make more precise adjustments by turning the Azimuth and Elevation nuts such that

each ¼ turn is equal to an adjustment of 0.25°.

There are two M8 Elevation Screws and two M8 Azimuth screws, as shown in Figure 5. Before starting the

alignment, make sure these screws are securely in place so they will not fall out during the procedure, but not too

tight, so as to enable you to manually adjust the azimuth and elevation to the approximate position you want,

before performing exact antenna alignment as described in the following sections.


Torque Requirements

phn-4026 003v000 Page 5-42

Upon delivery, the installation and alignment device is aligned 45° downward (elevation) and straight ahead

(azimuth).

You can adjust the azimuth up to 45° in either direction by manually turning the azimuth base.


Torque Requirements

phn-4026 003v000 Page 5-43

Figure 6: Installation and Alignment Device – Azimuth Range

For wall mount installations, you can adjust the azimuth an additional 45° in either direction by changing the placement of the Azimuth Screws. This enables you to adjust the azimuth a full 90° in either direction. See Extending the Azimuth Range.

Figure 7: Installation and Alignment Device – Extended Azimuth Range

You can adjust the elevation from the delivery position of 45° downward to a position as far as 45° upward. Be sure

to attach the RFU-E radio and antenna to the installation and alignment device before adjusting the elevation,

otherwise the weight of the radio and antenna might accidently reduce the elevation angle.
